Abstract In this study, the thermal-hydraulic performance of eight different printed circuit heat exchanger (PCHE) configurations with supercritical liquefied
natural gas as the working fluid are studied by a numerical method. Firstly, the thermal-hydraulic performance of the PCHE with different airfoil fins
are investigated at different operating pressures, which indicate that the PCHE with airfoil fins has better thermal performance but worse hydraulic
performance when it operates at higher pressure condition. Furthermore, the effects of different airfoil configurations on the thermal-hydraulic
performance are analyzed in detail. The results show that asymmetric airfoils can provide better heat transfer performance than symmetrical airfoils.… More >
